Japan 2027年十月公共假日

十月 2027 in Japan runs 31 calendar days, Northern-hemisphere autumn and Southern-hemisphere spring. Japan observes one public holiday in 十月 2027: Sports Day. One of those — Sports Day — falls on a weekday and reduces the working-day count by one. That leaves 20 working days for Japan businesses, payroll cycles, and project schedules in 十月 2027. October hosts Indigenous Peoples' Day / Columbus Day in the Americas on the second Monday and Reformation Day in northern-European Protestant traditions on the 31st.
